Struct GeomCount 

pub struct GeomCount {
    pub color: (u8, u8, u8),
    pub alpha: f64,
    pub min_size: f64,
    pub max_size: f64,
}

Count geometry — draws points sized by the number of overlapping observations.

Fields

color: (u8, u8, u8)

alpha: f64

min_size: f64

max_size: f64

Trait Implementations

impl Default for GeomCount

fn default() -> Self

Returns the “default value” for a type.

impl Geom for GeomCount

fn draw( &self, data: &DataFrame, coord: &dyn Coord, scales: &ScaleSet, _theme: &Theme, backend: &mut dyn DrawBackend, ) -> Result<(), RenderError>

Draw this geometry.

fn required_aes(&self) -> Vec<Aesthetic>

Required aesthetics.

fn default_stat(&self) -> Box<dyn Stat>

Default stat for this geom.

fn default_position(&self) -> Box<dyn Position>

Default position adjustment.

fn default_params(&self) -> GeomParams

Non-mapped visual defaults.

fn name(&self) -> &str

Name for debug/display.

fn set_series_color(&mut self, color: (u8, u8, u8))

Apply a brand/primary color to this geom’s single-series default (its color or fill). The build pipeline calls this only when the layer has no color/fill aesthetic mapped, so an explicit mapping always wins. The default is a no-op; series geoms override it.

fn include_zero_baseline(&self) -> bool

Whether this geom draws from a 0 baseline, so the Y scale should include 0 even when y is explicitly mapped (bars/columns/area/histograms — as in ggplot2). Default false.
